Referral targeting allows you to show a particular message to a visitor based on which website they came to your website from. 

Whether they found you on Google, Tripadvisor, or another website, you can greet each visitor with a unique targeted message based on where they came from. Just head to the Message Builder and select Referral website in the Audience section, then enter the URL of the referral website you would like to target visitors from.
